DEVICE AND METHOD FOR DETECTING SCENE CHANGE, IMAGE PROCESSOR, PROGRAM AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a new device and method for detecting a scene change by utilizing header information of encoded data of a moving image that is compressed and encoded. SOLUTION: An information acquiring part 111 extracts one or more pieces of specific header information from encoded data of the moving image by Motion-JPEG2000. The information acquiring part 111 outputs the extracted header information and/or one or more specific feature variables determined based on the extracted header information, and the extracted header information and/or the specific feature variables are inputted to a comparison and determination processing part 113 and temporarily stored in an information temporarily storing part 112. The comparison determination processing part 113 compares the header information and/or feature variables with each other between the current frame and the preceding frame, thereby determining whether a scene change occurred in the current frame. It is possible to detect various scene changes at a high speed. COPYRIGHT: (C)2004,JPO
